A project 30 years in the making, this tiny off-grid retreat on a coastal island in Maine is almost entirely self-sufficient. Designed and built by Alex Porter for her father. The project features a shed roof and is wrapped in a distinctive blue-grey corrugated skin. Dwell recently profiled the home, which is the only solar-powered retreat on the isolated island – its sustainable power source actually makes life a lot more leisurely, as the family does not need to schlep in fuel to run a noisy generator. They didn’t give anything up, as they have all the conveniences of a regular home — but with a view you don’t get in an everyday residence.
